As long as you don't whip it out for stupid reasons, you should be fine. I went to a more liberal school in a very liberal state, and I openly carried my BM's clipped to my right f.p. and never had any issues.. Then again, I never showed anyone, nor did I use it in public - reasons why most would cause sheeple to complain.
Just don't use your blade at the dining hall when they offer silver-wear, that's what I mean when I say "stupid reasons." Once your out of school, carry all you want - just be smart about it while "at" school.. My .2
